Sender Policy Framework, or SPF, is a verification system, which is employed to prevent the so-called e-mail spoofing where an email message can be sent from one e-mail address, but to appear as being sent from another one, frequently with the objective to scam the recipient for some reason. When SPF protection is enabled for a domain name, a unique record is made for it in the Domain Name System and all DNS servers globally have it. The record contains all the email servers that are permitted to send valid messages from an e-mail address part of the domain. When a message is sent, the very first DNS server it goes to checks the SPF record and in case the sending server is permitted, the message is sent to the target destination. When, however, the sending server is not present in the SPF record for the particular domain, the e-mail message won't be forwarded and it'll be removed. In case you employ this solution, it will prevent third parties from sending spam messages that appear to have been sent from you.
SPF Protection in Hosting
If you host your domains in a hosting account with us and we manage the e-mail addresses for them, you will be able to activate SPF protection for any of them with several clicks in your Hepsia Control Panel. The service can be found in a separate section where you can view which domains are already protected. For the ones which aren't, you can activate the SPF protection service and configure various things at the same time - the hostnames of the mail servers that are permitted to send messages from your mailboxes, the IPv4 and IPv6 addresses of these servers, and to create a rule that email messages can be sent only if your domains use our MX records. The last solution is the most secure one, and you can use it if we take care of the email addresses for your domains and you are not using another e-mail service provider. The new records will propagate within 24 hours and nobody will be able to fake the FROM field in an e-mail by using your addresses.
SPF Protection in Semi-dedicated Hosting
The SPF protection attribute is provided with all the Linux semi-dedicated hosting packages, so in case you host your domain names in an account on our cloud hosting platform, you are able to activate this service without difficulty for all of your domains. The Hepsia Control Panel, which is provided with the semi-dedicated accounts, has a rather easy to work with interface, therefore you will not need to be tech-savvy in order to protected your e-mails. You'll only need to type the hostname and the IP of each mail server that you would like to be certified to send out emails from your addresses and right after that the updated record will be activated for the domain that you've picked. As a further option, we will also give you the ability to restrict your outgoing email messages and protect your mailboxes further by allowing e-mail messages to be sent only when the domain involved has our MX records i.e. the emails for the domain name have to be managed here and not by some other supplier. Thus you'll enjoy even superior control and there won't be any chances for any person to forge your e-mail addresses for malicious purposes.
